Whereas wildlife sanctuary is a place where animals live in a natural habitat.

Q. Differentiate between endangered and extinct species.

Ans: Endangered species are those which are at the verge of extinction and are to be  protected.  E.g Hangul.

Q. What will happen if the top layer of soil is exposed?

Ans: If the top layer of soil is exposed, It will wash away.
The fertile land will turn into desert.

Q. Why should we conserve biodiversity.

Ans: The variety in life existing on the earth is referred to as biodiversity. We should conserve biodiversity  to maintain the food chain and conserve ecosystem.

Deforestation leads to desertification and habitat loss and increases global warming.

Q. What is Red data book?

Ans: Red Data Book is the record of all the endangered animals and plants. It is mantained by IUCN.

Q. What do we understand by term migration?

Ans: Migration is periodic movement of   some birds and animals move from one place to  other for the purpose of breeding or due to weather change.

Q. Explain how deforestation leads of reduced rainfall?

Ans: Due to deforestration, the water cycle will be disturbed. There will be no transpiration to mantain water cycle.
